Print settings
- INFINAM® TI 5400 L is designed to print on bottom-up digital light processing (DLP) machines.
- When printing with a light intensity of 2.4 mW/cm2 at 405 nm, the recommended layer exposure time for 100 μm thick layers is 2.4 s.
- Working curve data for 405 nm wavelength and 2.4 mW/cm2 intensity: Critical exposure energy Ec = 2.0-2.5 mJ/cm2 and Depth of penetration Dp = 200-250 μm.
Washing procedure
- It is recommended to wash printed parts with tripropylene glycol methyl ether (TPM) to remove uncured resinous materials.
- Recommend wash cycle: use 2 to 3 rinse buckets (from dirty soak to clean soak), each rinse for 2 to 5 minutes.
- Lastly, wash the 3D-printed object with isopropanol (IPA) for 2 minutes to remove excess TPM.
- After IPA wash, allow parts to dry for at least 30 minutes in order for the IPA to fully evaporate before the next post-curing process.
- Over-soaking or over-washing may result in loss in the mechanical properties.
- When support structures are used, they should be removed before postcuring.
Post-curing procedure
- After washing, the parts should be submitted to ultraviolet (UV) light (intensity at ca. 5 mW/cm2) for 120 min at 80 °C, followed by 180 min at 80 °C without UV light.

Mechanical testing measurements
- The mechanical values reported in this document were obtained on specimens printed with a DLP printer at 405 nm (2.4 mW/cm2, XY or XZ print with 2.4 s layer exposure time, 100 μm thick layers).
- Tensile bars were tested following ASTM D638, Type V, 10 mm/min using an automated extensometer.
- Specimens are notched using a manual notching machine.
Statement on reported mechanical and thermal properties
- The mechanical and thermal values reported in this document derived from printing various parts with one specific bottom-up DLP machine and following the above-mentioned procedures.
- Those values reflect an approximation of the mean value of a range of values and are intended for reference and comparison purposes only.

Storage & Handling
- Storage and Handling Information
- INFINAM® TI 5400 L resin is a light-sensitive product protected by its original packaging.
- Exposure of the liquid formulation to daylight or UV light should be minimized or avoided at all during storage and handling to ensure consistent print quality.
- Special light sources shall be used instead.
- Store product in a dry location with optimum storage temperature of 10-30 °C.
- Storage beyond this recommended temperature range can adversely affect both print and product properties.
- It is recommended to shake INFINAM® TI 5400 L resin well before use.
- Degassing can be carried out before any print process.
- It is advisable not to store the unused resin in the vat, especially for prolonged period of usage.
- If the resin is left in the vat after printing, thoroughly mix and agitate the resin in the vat prior to any print processes.
- Do not return used resin from the vat back into the original INFINAM® TI 5400 L container.
